Sinicization, reliability and validity of nursing-related quality of life scale in nursing institutions for the aged.

Objective To Chinesize the Nursing Home Care-related Quality of Life Scale (NHC-QoL) and to test its reliability and validity. Methods According to the Brislin model, the NHC-QoL scale was translated into Chinese and cross-cultural debugging was carried out. Using convenience sampling method, 198 elderly people from 4 nursing institutions in Shiyan city were investigated by questionnaire from March to July 2023 to evaluate the reliability and validity of the scale. Results There were 14 items in the Chinese version of NHC-QoL. The content validity index of each item was 0.7-1.0, and the content validity index of the scale was 0.929. Exploratory factor analysis extracted 5 common factors, which could explain 67.914% of the total variation. After discussion within the research group, the common factors were reduced to 2 common factors namely environment and service (11 items) and social interaction (3 items). The total Cronbach's α coefficient of the scale was 0.758 and the test-retest reliability was 0.783. Conclusion The Chinese version of NHC-QoL scale has good reliability and validity and can be used to evaluate the quality of life of the elderly in nursing institutions. [ABSTRACT FROM AUTHOR]
